Электрический генератор ProTorque Inboard/Outboard 12 В, 105 А Mercruiser/Delco

Very good value for money, amps. VIsually it looks okay. When I rotate the rotor, there’s a periodic noise, like something is catching inside. There’s also a sharper sound — I hope that’s from the brushes and will settle with use. As for the periodic noise, I hope it’s from the bearings because they haven’t been used, and it will smooth out after some running. In the end, I’m sending it for repair to have the bearings replaced. I hope it’s nothing else more serious that can’t be fixed.
